IMPROVED VEGETA'BLE-CRUSHER.

The Schedule referred to in these Letters Patent and making part of the same To all whom 'it ma/y concern:

Figure 2 -is a vertical section of the same, taken through the line x x, fig.,1.

Similar letters of reference indicate corresponding parts. My invention has forits object to furnish au improved machine, by means of which apples and other fruits, wheat, buckwheat, corn, &c., may be crushed; and

It consists in so constructing and arranging two ribbed rollers that they shall mutually scrape or clean -each other while the fruit or otlier substance is being crushed or squeezed between the ribs thereof, as will be hereinafter more fully described. v

A is the frame of the machine, which supports the operating-parts, and to which the bearings of therollers are attached in the ordinary manner.

B is the upper and larger roller, which revolves in bearings attached to the frame A, and to the projecting end of'one of the journals of which, the crank-wheel C is attached.4 Y

The crank-wheel C should be made large so as to serve at the same time as a {1y-wheel.v

D is the lower or smaller roller, which is placed directly beneath the roller B, and the journals of which revolve in adjustable bearings attached to the frame A, so that the roller D may be moved nearer to or further 'om the roller B, as may be desired, reference I. being had to the work to be done.

The roller is made of about twice thediameter of the rollerD, and to the faces of both rollers are attached, or upon them are formed longitudinal iianges or teeth, the number of saidanges or teeth being the same upon one roller as upon the other.

To the projecting end of the journaloi the roller B .is attached a gear-wheel, E, the teeth of which mesh teeth of each roller to scrape over the surface or space between the flanges or teeth of the other roller, thus keeping the faces ofthe rollers clear-and preventing all clogging.

G is a stationary hopper, attached to the upper part oi the frame A, into which the materialto be crushed is placed, and from which it is conducted to the rollers through the scroll-hopper H.

lhe scroll-hopper H is made in about the shape shown inthe drawings, and is pivoted at its upper end to the frame A, as shown in dotted lines in fig. 2.

The smpll-hopper is so formed as-to overlap the ends of the roller B, while its lower end terminates in the space between the said rollers B and D, as' shown in li 2.

gThe' throat of the hopper H, or the space between said hopperand the roller B, gradually decreases in size, so that the material passing through it may be gradually attened or reduced to such a shape that it may readily enter between the rollers B and D, to be vcrushed by said'rollers.

said beam is so formed'and placed as to form a contin nation ofthe throat of the hopper H, when said hopper is pushed back. l

J is a grinding-mill placed.Y beneath the roller D, iu such a position as to receive the crushed material as it comes from the rollers B and D, and hull it or grind it to the desired finenS.

In the drawings the mill J is represented as an ordi-pl nary cone or coffee-mill, but its form is immaterial.

The mill J is driven by a ear-w'lleel K, of the same size as the gear-wheels and-F, theteeth of which mesh into the teeth' of the gearLwheel F, as.

shown in iig. 1, or in anyother convenient way.

` The grinding-mill J is used for grinding or hulling corn, wheat, buckwheat, and other material that requires to be ground or hulled, after being crushed by passing between the rollers B and D.

When apples, audother material that does not require to be ground, are passed through the machine, the milll J should be detached and removed. A

I claim as new, and desire to secure by Letters Pat tent- Y Two or more crushing-rollers of different diameters, provided with au equal number of ribs, and arranged and operated in s uch a manner that they shall make the same numberoi' revolutions, and the respective ribs scrape or clean the opposite roller while the fruit or other substance is being crushed between said ribs,

- substantially .as specified.

The above specification of my invention signed byv me, this 11th day of February, 1868.
